Measurements of (He3,d) reactions can provide information on the proton widths of states that play a role in astrophysically important (p,γ) reactions. We report on the first study of the (He3,d) reaction in inverse kinematics with a Ni56(T1/2=6.1 d) ion beam. The Q-value resolution of ~keV achieved in this experiment was sufficient to separate the transitions populating the ground state and the 1/2 - 5/2- doublet at Ex~1.1 MeV in Cu57. Prospects for similar (He3,d) experiments with improved energy resolution are also discussed
